HB 571 addresses several privacy issues, including the use of automatic license plate readers (ALPR), which store photographs, the license plate numbers, and the date, time, and location of vehicles. A single scanner can capture hundreds of license plate numbers in a matter of hours. HB 571 also prohibits the use of wall-penetrating radar (with allowed exceptions). HB 571 prohibits collection of electronic data without a warrant and make any warrantless data obtained by a state agency inadmissible in court.
